SAFETY-RAZOR.

To all whom it may concern:

Be it known that I, WILBRAND H. ALDEN- DORF, resident of Dormont, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Safety-Razors, of which the following is a specification.

This invention relates to safety razors of the type in which the blade is at right angles to the handle.

The objects of the invention are to provide a safety razor of this type which is composed of a few parts of simple construction and is, therefore, cheap to manfacture and easy to keep clean, one which is readily reversible, without taking the same apart, one in which the inactive. edge of the blade is shielded so that the user cannot accidentally cut himself, and one which possesses other advantages hereinafter set forth. 7

In the drawings, F igure 1 is an elevation of" the razor looking at the guard plate in end view; Fig. 2 is a similar view showing the head in transverse section;.Fig. 3 is a view showing the head of the razor in plan; Fig. 4: is an inverted plan view of the blade and shield and illustrating the manner in which the blade is held by the shield; Fig. 5 is an inverted plan view of the guard plate, blade and shield, showing the manner of securing the blade and shield to the guard; and Fig. 6 is a section on the line 6-6, Fig. 3. g

The razor illustrated comprises a handle 1, a guard plate 2, a blade 3, and a blade parts are preferably made of metal or other material which can be sterilized and rendered perfectly sanitary.

The handle 1 is a plainsolid bar or rod of metal, without cavities or. bores, and is provided with the reduced threaded end portion 5 by means of which it is detachably connected to the guard plate 2. This guard plate is of approximately concave or'convex form in cross section, or otherwise formed so that its two side portions, that is, the portions at opposite sides of its longitudinal center, are disposed at an angle to each other, as shown 'in Figs. 1 and 2, and both edges are provided with series of projecting guard teeth 6, as is usual with guards for safety razors, This guard plate is provided centrally with a threaded opening 7 for receiving the threaded end 5 of the'handle.

The blade 3 is of the double edged variety,

and is disposed on the outer or concave side of the guard plate, and when in use has its active cutting edge partly overlying the guard teeth on that side of the guard. The, blade is overlaid by the shield 4, which is of such width that it permits the active edge of the blade to project beyond. one of its edges while the opposite or'inactive edge of the blade is completely covered so that the user is not liable to cut himself with this edge.

The shield is provided at its ends with downturned guide lugs 8 for the blade and between said guide lugs with turned-under shown in Fig. 5 and serve to secure the shield to the guard plate. The blade is held in adjusted position by means of the thread ed end 5 of the handle, which, when it is screwed fully inwardly, engages the blade rearwardly of its longitudinal center, and. thus tilts or cants the blade and shield, brings the forward or active edge of the blade into operative relation to the guard teeth, and clamps the blade and shield firmly in position.

The ends of the guard plate, at its longitudinal center, are provided with notches 10 of sufficient depth to permit the hook lugs 9 to pass therethrough in order to engage on the under surface of said plate, and at both sides of said central notches are shoulders 11 against which the hook lugs 9 abut and which serve as stops to limit the movement of the blade and shield toward the active side of the guard plate, the blade itself being held in -proper relation to the shield by means of notches or recesses 12 in its ends, which engage the downturned hook lu 9. These recesses 12 permit the use of a blade of substantially the same length as the shield to be inserted between the lugs 9,. and are of greater width than said lugs to allow sufficient movement of the blade relative to the shield to expose one edge when the blade and shield are adjusted from one side of the guard to the other when it is desired to usethe other cutting edge.

The parts are assembled by first inserting a blade 3 in the shield. with its notches 12 engaging the hook lugs .9, and then passing said lugs through the notches 10 in the guard plate, and then moving the shield and blade toward one side or the other so as to bring the ends of the lugs 9 underneath the guard plate, and finally screwing the handle v1' full inwardly, thus tilting the. shield and b ade around the lugs 9 as a'fulcrunr and clamping the active edge of the blade n proper'operative position with reference to the guard teeth on that side of the guard.

The blade can be'readily reversechwithout taking'the razor apart, by partially unscrew ing the handle 1, and then swinging the shield over to the other side. Inasmuch as the blade is interlocked with the slneld, 1t

' moves with it, and when the shield reaches adjusted position.

its opposite position, the blade automatically adjusts itself (by reason of the notches 12 being wider than the lugs 9), toexpose its opposite edge in operative relation to the guard teeth on that side of-the guard, after which the handle is screwed fully inwardly to clamp the shield and blade in this newly The razor described is of 'very simple construction, comprising only three parts ing, and, therefore, maintained in a sani tary condition. Both edgesv ofthe blade a new blade;

, struction is such that most all standard,

in addition to the blade. All; of these parts are of very simple form and can therefor be .cheaply fabricated. They are en-' tirely. free from recesses,-bore's and the like, so that they can be readily cleaned by wlpcan be utilized and the adjustment from one edge to the other can be. made' very quickly and easily. The blade can be readily removed for cleaning or replacing with The construction permlts the use of thick-blades, which give better edges and may be re-sharpened t6 better advantage than very thin blades, and the conblades can be'used. At the same time the inactive edge of the blade is covered by the shield so that accidental cutting by the back.

' edge of the blade is avoided.

Various changes can obviously be made in the shape and details of construction of the parts, and particularly as the specific Way of connecting the shield tothe guard plate without departing from the invention ing.

as defined in the claims hereinafter follow:
